Description

本発明は、容器内部に熱を蓄積するための蓄熱容器に関する。 The present invention relates to a heat storage container for accumulating heat inside the container.

従来、熱電素子を用いて容器内部を冷却及び放熱することにより容器内部の温度を調整する技術が知られている（例えば、特許文献１参照）。 Conventionally, there is known a technique of adjusting the temperature inside a container by cooling and dissipating heat inside the container using a thermoelectric element (see, for example, Patent Document 1).

特開２００１−３４９６５３号公報Japanese Unexamined Patent Publication No. 2001-349655

特許文献１に記載の容器は、熱電素子を用いて容器内部の温度を調整することができるが、容器内部に熱を蓄積することには適していない。容器内部に熱を蓄積するための蓄熱容器は、例えば、容器内部と容器外部との間に真空層を設けた断熱構造を有している。 The container described in Patent Document 1 can adjust the temperature inside the container by using a thermoelectric element, but is not suitable for accumulating heat inside the container. The heat storage container for accumulating heat inside the container has, for example, a heat insulating structure in which a vacuum layer is provided between the inside of the container and the outside of the container.

しかし、このような蓄熱容器において、外気又は熱源と接触する部分（例えば、蓄熱容器の蓋）は、蓄熱容器の高温側から低温側へ熱流束が生じるので、蓄熱容器の内部の熱が蓄熱容器の外部へ逃げやすいという問題が生じていた。 However, in such a heat storage container, heat flux is generated from the high temperature side to the low temperature side of the heat storage container at the portion in contact with the outside air or the heat source (for example, the lid of the heat storage container), so that the heat inside the heat storage container is transferred to the heat storage container. There was a problem that it was easy to escape to the outside of the.

そこで、本発明はこれらの点に鑑みてなされたものであり、蓄熱容器に蓄積された熱の保温性能を向上させることを目的とする。 Therefore, the present invention has been made in view of these points, and an object of the present invention is to improve the heat retention performance of the heat stored in the heat storage container.

本発明の第１の態様の蓄熱容器は、発熱部を包囲する断熱構造と、前記断熱構造に形成された開口部に収容可能な蓋と、を備え、前記蓋は、一端と他端との温度差に応じて電力を発生する熱電素子と、前記熱電素子が発生した電力により熱を発するヒータと、を有する。 The heat storage container of the first aspect of the present invention includes a heat insulating structure surrounding the heat generating portion and a lid that can be accommodated in the opening formed in the heat insulating structure, and the lid has one end and the other end. It has a thermoelectric element that generates electric power according to a temperature difference, and a heater that generates heat by the electric power generated by the thermoelectric element.

また、前記熱電素子は、前記ヒータよりも前記開口部から遠い位置に設けられてもよい。 Further, the thermoelectric element may be provided at a position farther from the opening than the heater.

また、前記熱電素子は、前記蓋において前記開口部から最も遠い側に設けられており、前記ヒータは、前記蓋において前記開口部に最も近い側に設けられてもよい。 Further, the thermoelectric element may be provided on the lid on the side farthest from the opening, and the heater may be provided on the lid on the side closest to the opening.

また、前記ヒータは、前記熱電素子が発した電力に加えて、外部電源から供給される電力により熱を発してもよい。 Further, the heater may generate heat by electric power supplied from an external power source in addition to the electric power generated by the thermoelectric element.

また、前記蓄熱容器は、車両に搭載されており、前記断熱構造は、前記発熱部としての前記車両の内燃機関を包囲してもよい。 Further, the heat storage container is mounted on the vehicle, and the heat insulating structure may surround the internal combustion engine of the vehicle as the heat generating portion.

本発明によれば、蓄熱容器に蓄積された熱の保温性能を向上させることができるという効果を奏する。 According to the present invention, there is an effect that the heat retention performance of the heat stored in the heat storage container can be improved.

［蓄熱容器の構成］
図１は、本実施形態に係る蓄熱容器１の構成を示す図である。蓄熱容器１は、内部に熱を蓄積することを目的としている。図１に示すように、蓄熱容器１は、断熱構造１１と、開口部１２と、蓋１３とを有する。 [Structure of heat storage container]
FIG. 1 is a diagram showing a configuration of a heat storage container 1 according to the present embodiment. The heat storage container 1 is intended to store heat inside. As shown in FIG. 1, the heat storage container 1 has a heat insulating structure 11, an opening 12, and a lid 13.

断熱構造１１は、発熱部Ｈを包囲しており、発熱部Ｈが発する熱の外部への伝達を遮断する。具体的には、断熱構造１１は、内壁１１１と外壁１１２との間に真空層１１３を有しており、真空層１１３により発熱部Ｈが発する熱の外部への伝達を遮断する。 The heat insulating structure 11 surrounds the heat generating portion H and blocks the transmission of heat generated by the heat generating portion H to the outside. Specifically, the heat insulating structure 11 has a vacuum layer 113 between the inner wall 111 and the outer wall 112, and the vacuum layer 113 blocks the heat generated by the heat generating portion H from being transmitted to the outside.

発熱部Ｈは、蓄熱容器１の内部に設けられ、熱を発する。発熱部Ｈが発した熱は、断熱構造１１及び蓋１３に伝達される。発熱部Ｈは、例えば、内燃機関、ヘッドランプ又はアクチュエータ等の作動時に熱を発する車両の構成部材である。 The heat generating portion H is provided inside the heat storage container 1 and generates heat. The heat generated by the heat generating portion H is transferred to the heat insulating structure 11 and the lid 13. The heat generating portion H is, for example, a component member of a vehicle that generates heat when an internal combustion engine, a headlamp, an actuator, or the like is operated.

開口部１２は、断熱構造１１の一部に形成されており、蓋１３を収容可能である。
蓋１３は、開口部１２に収容され、開口部１２に収容された状態で、一方の面が発熱部Ｈに接し、他方の面が蓄熱容器１の外部と接する。蓋１３は、発熱部Ｈと蓄熱容器１の外部との間に収容されるので、蓄熱容器１の高温側（発熱部Ｈ側）から低温側（外部側）へ熱流束が生じることにより、蓄熱容器１の内部の熱が蓋１３を介して蓄熱容器１の外部へ伝達される。 The opening 12 is formed in a part of the heat insulating structure 11 and can accommodate the lid 13.
The lid 13 is housed in the opening 12, and in a state of being housed in the opening 12, one surface is in contact with the heat generating portion H, and the other surface is in contact with the outside of the heat storage container 1. Since the lid 13 is housed between the heat generating portion H and the outside of the heat storage container 1, heat is stored by generating heat flux from the high temperature side (heating portion H side) to the low temperature side (outside side) of the heat storage container 1. The heat inside the container 1 is transferred to the outside of the heat storage container 1 through the lid 13.

［蓋の構成］
図２は、本実施形態に係る蓋１３の構成を示す図である。具体的には、図２（ａ）は、蓋１３の詳細な構成を示す図であり、図２（ｂ）は、蓋１３付近で伝達される熱の温度勾配を示す図である。図２（ａ）に示すように、蓋１３は、断熱部材１３０と、熱電素子１３１と、ヒータ１３２と、電圧変換部１３３とを有する。 [Lid configuration]
FIG. 2 is a diagram showing the configuration of the lid 13 according to the present embodiment. Specifically, FIG. 2A is a diagram showing a detailed configuration of the lid 13, and FIG. 2B is a diagram showing a temperature gradient of heat transferred in the vicinity of the lid 13. As shown in FIG. 2A, the lid 13 has a heat insulating member 130, a thermoelectric element 131, a heater 132, and a voltage conversion unit 133.

断熱部材１３０は、熱電素子１３１とヒータ１３２との間に設けられ、断熱材で構成される。 The heat insulating member 130 is provided between the thermoelectric element 131 and the heater 132, and is composed of a heat insulating material.

熱電素子１３１は、ヒータ１３２よりも開口部１２から遠い位置に設けられており、電圧変換部１３３を介してヒータ１３２と電気的に接続されている。熱電素子１３１は、例えば、ゼーベック効果を利用して、蓋１３の一端（高温側）と他端（低温側）との温度差に応じて電力を発生する。熱電素子１３１は、例えばＢｉ−Ｔｅ系、Ｐｂ−Ｔｅ系又はＳｉ−Ｇｅ系等の熱電変換材料で構成される。 The thermoelectric element 131 is provided at a position farther from the opening 12 than the heater 132, and is electrically connected to the heater 132 via the voltage conversion unit 133. The thermoelectric element 131 uses, for example, the Seebeck effect to generate electric power according to the temperature difference between one end (high temperature side) and the other end (low temperature side) of the lid 13. The thermoelectric element 131 is made of, for example, a thermoelectric conversion material such as Bi-Te type, Pb-Te type, or Si-Ge type.

ヒータ１３２は、蓋１３において開口部１２に近い位置に設けられており、電圧変換部１３３を介して熱電素子１３１と電気的に接続されている。ヒータ１３２は、熱電素子１３１が発生した電力により熱を発する。 The heater 132 is provided at a position close to the opening 12 in the lid 13, and is electrically connected to the thermoelectric element 131 via the voltage conversion unit 133. The heater 132 generates heat by the electric power generated by the thermoelectric element 131.

電圧変換部１３３は、例えば、直流変換器（ＤＣ−ＤＣコンバータ）及びレギュレータ等を含む。電圧変換部１３３は、熱電素子１３１が発生した電力をヒータ１３２で使用可能な電圧に変換し、変換後の電圧をヒータ１３２に供給する。 The voltage converter 133 includes, for example, a DC converter (DC-DC converter), a regulator, and the like. The voltage conversion unit 133 converts the electric power generated by the thermoelectric element 131 into a voltage that can be used by the heater 132, and supplies the converted voltage to the heater 132.

熱電素子１３１は、蓋１３において開口部１２から最も遠い側に設けられており、ヒータ１３２は、蓋１３において開口部１２に最も近い側に設けられていることが好ましい。蓋１３がこのように構成されていることで、蓋１３の一端と他端との温度差が大きくなり、熱電素子１３１が発生する電力を大きくすることができる。 It is preferable that the thermoelectric element 131 is provided on the lid 13 on the side farthest from the opening 12, and the heater 132 is provided on the lid 13 on the side closest to the opening 12. When the lid 13 is configured in this way, the temperature difference between one end and the other end of the lid 13 becomes large, and the electric power generated by the thermoelectric element 131 can be increased.

ここで、蓋１３における熱流束と温度勾配との関係について説明する。蓋１３は、厚さに比べて面積が大きく、熱が厚さ方向にのみ１次元的に伝達されると仮定することができる。また、蓋１３は、一定の熱伝導率を有し、熱が蓋１３全体に伝達されると仮定することができる。 Here, the relationship between the heat flux and the temperature gradient in the lid 13 will be described. It can be assumed that the lid 13 has a larger area than the thickness and heat is transferred one-dimensionally only in the thickness direction. Further, it can be assumed that the lid 13 has a constant thermal conductivity and heat is transferred to the entire lid 13.

このような場合、蓄熱容器１の高温側から低温側へ熱流束が生じると、蓋１３付近において、図２（ｂ）に示すような温度勾配が生じる。図２（ｂ）の温度勾配Ａは、熱電素子１３１及びヒータ１３２が動作していないときの温度勾配であり、温度勾配Ｂは、熱電素子１３１及びヒータ１３２が動作しているときの温度勾配である。 In such a case, when a heat flux is generated from the high temperature side to the low temperature side of the heat storage container 1, a temperature gradient as shown in FIG. 2B is generated in the vicinity of the lid 13. The temperature gradient A in FIG. 2B is the temperature gradient when the thermoelectric element 131 and the heater 132 are not operating, and the temperature gradient B is the temperature gradient when the thermoelectric element 131 and the heater 132 are operating. is there.

熱電素子１３１が電力を発生し、発生した電力によりヒータ１３２が熱を発すると、蓋１３全体が加熱されるので、蓋１３の内部の温度差が減少し、蓄熱容器１の高温側から低温側へ生じる熱流束が緩和される。その結果、蓋１３における温度勾配Ｂは、蓋１３における温度勾配Ａよりも緩やかな変動となる。このように蓄熱容器１は、ヒータ１３２が発する熱により蓄熱容器１の高温側から低温側へ生じる熱流束を緩和することができるので、蓄熱容器１に蓄積された熱の保温性能を向上させることができる。 When the thermoelectric element 131 generates electric power and the heater 132 generates heat by the generated electric power, the entire lid 13 is heated, so that the temperature difference inside the lid 13 is reduced, and the high temperature side to the low temperature side of the heat storage container 1 is reduced. The heat flux generated in is relaxed. As a result, the temperature gradient B on the lid 13 fluctuates more gently than the temperature gradient A on the lid 13. In this way, the heat storage container 1 can relax the heat flux generated from the high temperature side to the low temperature side of the heat storage container 1 due to the heat generated by the heater 132, so that the heat retention performance of the heat accumulated in the heat storage container 1 can be improved. Can be done.

蓄熱容器１は、例えば車両に搭載されており、断熱構造１１は、発熱部Ｈとしての車両の内燃機関を包囲する。車両にこのような蓄熱容器１が設けられていることで、アイドリング中における内燃機関の保温性能が向上する。また、蓄熱容器１は、ヘッドランプ、作動しているアクチュエータの近傍等のような車両において熱を蓄積することを必要とする部位に適用されてもよい。 The heat storage container 1 is mounted on the vehicle, for example, and the heat insulating structure 11 surrounds the internal combustion engine of the vehicle as the heat generating portion H. By providing such a heat storage container 1 in the vehicle, the heat retention performance of the internal combustion engine during idling is improved. Further, the heat storage container 1 may be applied to a portion that requires heat storage in a vehicle such as a headlamp, a vicinity of an operating actuator, or the like.

［変形例１］
図３は、蓋１３の変形例の構成を示す図である。図３に示す変形例では、蓋１３の電圧変換部１３３に外部電源１３４及び制御部１３５が接続されている。ヒータ１３２は、熱電素子１３１が発した電力に加えて、外部電源１３４から供給される電力により熱を発してもよい。このようにすることで、蓄熱容器１は、蓄熱容器１の高温側から低温側へ生じる熱流束による熱の変動量に相当する電力を熱電素子１３１により供給し、さらに加熱が必要な場合、外部電源１３４から供給される電力によりヒータ１３２を加熱することができる。 [Modification 1]
FIG. 3 is a diagram showing a configuration of a modified example of the lid 13. In the modified example shown in FIG. 3, the external power supply 134 and the control unit 135 are connected to the voltage conversion unit 133 of the lid 13. The heater 132 may generate heat by the electric power supplied from the external power source 134 in addition to the electric power generated by the thermoelectric element 131. By doing so, the heat storage container 1 supplies electric power corresponding to the amount of heat fluctuation due to the heat flux generated from the high temperature side to the low temperature side of the heat storage container 1 by the thermoelectric element 131, and when further heating is required, it is external. The heater 132 can be heated by the electric power supplied from the power source 134.

また、マイクロコンピュータ等で構成される制御部１３５が電圧変換部１３３及び外部電源１３４の動作を制御してもよい。例えば、制御部１３５は、内燃機関のアイドリング中には電圧変換部１３３及び外部電源１３４を動作させ、内燃機関のアイドリング停止時には電圧変換部１３３及び外部電源１３４の動作を停止させるように制御する。このようにすることで、蓄熱容器１は、ヒータ１３２の動作を切り替えることにより容器内部において熱を使う量を調節することができる。 Further, the control unit 135 composed of a microcomputer or the like may control the operation of the voltage conversion unit 133 and the external power supply 134. For example, the control unit 135 controls the voltage conversion unit 133 and the external power supply 134 to operate while the internal combustion engine is idling, and stops the operation of the voltage conversion unit 133 and the external power supply 134 when the internal combustion engine is idling. By doing so, the heat storage container 1 can adjust the amount of heat used inside the container by switching the operation of the heater 132.

［変形例２］
上述した実施形態では、熱電素子１３１は、蓋１３において開口部１２から最も遠い側に設けられており、ヒータ１３２は、蓋１３において開口部１２に最も近い側に設けられている。しかし、熱電素子１３１及びヒータ１３２が設けられる位置は、上述した位置に限定されない。 [Modification 2]
In the above-described embodiment, the thermoelectric element 131 is provided on the lid 13 on the side farthest from the opening 12, and the heater 132 is provided on the lid 13 on the side closest to the opening 12. However, the position where the thermoelectric element 131 and the heater 132 are provided is not limited to the above-mentioned position.

例えば、蓄熱容器１は、蓋１３において高温側と低温側との温度差が大きい側に熱電素子１３１を設けてもよい。具体的には、蓄熱容器１の外部に熱を奪いやすい媒体がある場合、熱電素子１３１は、蓋１３において開口部１２から最も遠い側に設けられてもよい。また、蓄熱容器１の発熱部Ｈに熱を奪いやすい媒体がある場合、熱電素子１３１は、蓋１３において開口部１２から最も近い側に設けられてもよい。 For example, the heat storage container 1 may be provided with the thermoelectric element 131 on the side of the lid 13 where the temperature difference between the high temperature side and the low temperature side is large. Specifically, when there is a medium that easily absorbs heat outside the heat storage container 1, the thermoelectric element 131 may be provided on the lid 13 on the side farthest from the opening 12. Further, when the heat generating portion H of the heat storage container 1 has a medium that easily absorbs heat, the thermoelectric element 131 may be provided on the lid 13 on the side closest to the opening 12.

このように蓄熱容器１は、高温側と低温側との温度差が大きい側に熱電素子１３１を設けることにより蓄熱容器１に蓄積される熱の保温性能を向上させることができる。また、蓄熱容器１において、発熱部Ｈに替えて、冷却材等が流れる低温部が設けられてもよい。このようにすることで、蓄熱容器１は、低温部の冷却性能を向上させることができる。 As described above, the heat storage container 1 can improve the heat retention performance of the heat stored in the heat storage container 1 by providing the thermoelectric element 131 on the side where the temperature difference between the high temperature side and the low temperature side is large. Further, in the heat storage container 1, a low temperature portion through which a coolant or the like flows may be provided instead of the heat generating portion H. By doing so, the heat storage container 1 can improve the cooling performance of the low temperature portion.

［蓄熱容器１による効果］
以上説明したように、蓄熱容器１は、一端と他端との温度差に応じて電力を発生する熱電素子１３１と、熱電素子１３１が発生した電力により熱を発するヒータ１３２と、を有する蓋１３を有している。このようにすることで、蓄熱容器１は、ヒータ１３２が発する熱により蓄熱容器１の高温側から低温側へ生じる熱流束を緩和することができるので、蓄熱容器１に蓄積された熱の保温性能を向上させることができる。 [Effect of heat storage container 1]
As described above, the heat storage container 1 has a lid 13 having a thermoelectric element 131 that generates electric power according to the temperature difference between one end and the other end, and a heater 132 that generates heat by the electric power generated by the thermoelectric element 131. have. By doing so, the heat storage container 1 can relax the heat flux generated from the high temperature side to the low temperature side of the heat storage container 1 due to the heat generated by the heater 132, so that the heat retention performance of the heat stored in the heat storage container 1 can be relaxed. Can be improved.
